SPECIFICATION forming part of Letters Patent No. 364,739, dated June 14, 1887.

Application ilol April 22,1884. Serial No.12?,887. (No model.)

'To all whom it may concern:

Be it known that I, 4BENJAMIN C. VANDU ZEN, a resident of Winton Place, in the county of Hamilton and State of Ohio, haveinvented certain new and' useful Improvements in Pumps, of which the following is a specification.

My improvements relate` to that class of .pumps known as double-acting forcepumps,77 and are especially applicable to deep wells. f Y

The several features of my invention and their use conjointly or otherwise will. be apparent from the following descriptionl and claims.

In theA accompanying drawings, Figure 1,

Sheet 1, represents a vertical central section ofthe upper portion ofthe pumpsection and lever, its immediate support not being shown. Fig. 2, same sheet, represents a vertical central section of the lower portion of the pump, said section being taken in the same plane as the section of Fig. 1 is taken. Fig. 3, Sheet 2, represents a vertical central section of the upper portion of said pump, said section being taken at the dotted line gr a: of Fig. 1 and at right angles to the plane of thesection of said Fig. 1, the lever and its immediate support not being shown, the actuating pumprod and connecting-rod being left in elevation. Fig. 4, same sheet, represents a vertical central section of the preferred form of joint for uniting lengths of pump piping or tubing. Fig. 5, Sheet 3, represents a horizontal transverse section of a part ofthepump,taken `at the dotted line g/ y, Fig. 1, and a plan of other adjacent parts of the pump, the View being from. above downward. Fig. 6, same sheet, represents a horizontal section of the lower piston, said section being taken at the dotted line z .e

v of Fig.` 2. Fig. 7 represents a vertical central section of the airyessel and dischargetube and a pump-stock and the chamber gfafthe pump.

A indicates the supporting-base, .connected in any suitable manner to the platform or equivalent support. A preferred mode of securing the base A to the platform consists in providing the base with holes B', through which bolts, screws, or rivets can be passed to secure the standard to a suitable platform, as

C. The supporting-base has a recess, D, at bottom, provided with space or recess D', and

yin this opening and fitting the sides thereof is secured, (preferably by screwthread,) the upper end of cylinder or tube E, whose function will be hereinafter described.

In the space or recess D isa device consisting of a hollow body, G, preferably circular f the bedpiece A by its own bolt a', passing down through a hole, a, in the arm and screwed into the bed-piece A." This bodypiece G at each sidesets upon shoulders b b of the bed A. Centrally located in the body G is a vvertical slot or opening, j', passing entirely'through the body G, and in this slot plays the actuatingrod H of the pump. This body-piece has a chamber, g, and there is no communication between this chamber g and slot f. This chamber communicates withtwo tubes, I I, one located on one side of the pump-rod I-I and the other on the other side of the said rod. Each of said tubes is connected to the body-piece G by suitable means. A preferred mode of connecting said tubes to said body G consists in providing the latter with tubular iaugcs or extensions h, and into each `tubular flange is screwed one (via, its respective) tube, I. The rear -end of this chamber communicates with chamber g of the bed-piece A. The chamber g communicates with a suitable discharge -spout and anair tube or vessel, the preferred combination of said chamber g', discharge-spout', and air-tube being as follows: Into this last-named chamber g open air tube or vessel 5, closed at top, and discharge-tube 4t, the latter communicating with the discharge spout of the pump. Preferably tube ltinclose's air-tube.. The points of juncture between the body or piece G and the adjacent ends or edges of the chamber g' are securely packed, preferably by means of a thin sheet or strips of packing, t', placed between thc adjacent edges of chambers gand g.

IOO

Suitable means are to be employed to press the body G- rearward, so that said edges of chamber f/ shall press against the adjacent edges of chamber g', and the preferred means for this purpose consists of a setserew, j, engaging a screw-thread in a portion, 7;, of the bed-piece A. The rear end of this setserew presses against the front end of the body-piece G, and forces the edges of chamber r/ of said body-piece G toward the adjacent edges of chambery', and thus compress the packing t. By making the said portion k of the bed-piece A broad and strong, and providing a recess in the front end of the body-piece G, and causing the end of the set-screw j to fit therein, the set-screw, when tightened, also assists in preventing the body -piece G from being lifted and from being moved laterally.

The tubes I I communicate below with a common ring or cylinder, J, and the connection between this rinfT J and each tube is pref'- erably a screw connection; but in any case it is a. water and air tight connection. In the center of this ring are two walls or partitions, ZZ, between which is a space, Z, in which the actuating pump-rod plays. These partitionsl Z entirely separate the space l from the passages m m of said cylinder J, and there is no direct communication between them. This cylinder J is provided exteriorly with a packing which prevents water or air from passing up between tube E and this cylinder J. The preferred mode of packing at for this purpose consists as follows: The lower portion of cylinder J is exteriorly provided with a surrounding recess, n, whose upper portion is deeper than its lower portion, the side of this recess being provided with a bevel or incline, n. In this recess lies a sheet of packing-n2, which fills the space between the side of lower edge of the cylinder and the interior surface of tube E. This packing also preferably extends a distance below the edge of cylinder J. Thus when liquid or air rises in the pump from below up to cylinder J the liquid or air must pass through its passages m m, and cannot pass between the outside of cylinder J and theinside of tube E,and any effort ofsaid liquid or air to pass between said cylinder J and tube E will cause the lower end or edge of the packing to be pressed more secure] y and tightly against the inside of tube E, thus more tightly and securely packing said joint between said cylinder J and tube E and the bet ter preventing any fiuid from passing through said joint.

The partitions l Z are rigidly connected at their lower ends to a tube, K, within which plays a piston, L, suitably packed,constructed, and connected to the pump-rod H. Prefer4 ably, the piston consists of a disk, p, having ing ears pp', between which ears is the lower end of the pump-rod, pivoted to said ears by a suitable pivot or bolt, as p2.

Into the piston is screwed from below the eonneetingrod M, and a packing, p, of the shape of an inverted cup, is located immedi ately below the piston and secured in place by a nut screwed onto pump-rod M and against the central portion of the said packing p. The lower end of tube E preferably is about opposite the piston L when the latter is at the upper end of its strokeand to this lower end of said tube E is connected the tube N, preferably of less diameter than the tube E. This tube N is continued down to the water or other liquid and passes down into the latter a desired distance. At or in its lower end is located a suitable valve, l). This valve is preferably a check-valve, and may be constructed as follows:

q indicates the valve-piece provided with packing q, centrally secured together by screw q2, the valve being hinged to its seat i' by a hinge or pivot, q. The valve-seat 1 carries an arch, q, overarching and spanning the valve. Through the valve-seat r is inlet-passage S, communicating with the water or other liquid of the well. In the present instance the valve-seat is continued downward in the form of an extension, i", which tapers or dif minishes in size toward its lower end. This extension r is preferably provided eXteriorly at top and bottom with annular outwardly-extending offsets 1', which latter when present rest against the interior of the terminal portion N of tube N. The slight intcrspace 1 between the upper and lower oft'- scts and the outside of extension 1" and the inside of terminal tube or portion N may be tilled with packing. A convenient mode of packing this space consists in wrapping waste about the extension r between the ofi'- sets and then pressing said extension 1" down to place in tube or portion N. This Valveseat o, with its extension 1", rests on and within the sides of the terminal portion N of thctubc N, this terminal portion being provided with shoulder t and female screw-thread t', the shoulder't preventing the extension N from being screwed too far onto tube N, and also admitting of packing, when desired, being placed between the lower end of tube N and the said shoulder. The terminal portion N is interiorly tapered correspondingly to the taper of the exterior of the valve-seat extension. Thus the valve-seat extension 7' becomes wedged in and supported by theterininal portion N. The passage 1t through extension o" and. passage a through terminal portion N connect with one another, and the said pas sage u opens out into the well and serves as the inlet to the pump. The lower end of terminal portion N is preferably provided with a broad annular flange or foot.

The rod M is continued down from upper piston, L, and is provided at its lower end with a suitable valve-piston, Q, a preferred form of which consists as follows: A plate or disk, V, is located on rod M, and upon this plate rests the lower part of a cupshaped annular packing, V. Above andloeated within the cup of the packing is a plate or disk, V. The disk V and disk V2 are screwed to rod M,

and, being screwed tightly toward each other, i

' disk V2 are openings, as z, (see Fig. 6,) andthe center of the packing V is also open. Thus when the piston Q is being depressed the liquid is permitted to flow upward through the openings z and through part of the valvepiece V3; but this valve-piece Va prevents anydownwardv flow of water through piston Q. That portion of the tubing or pipingin which valve-piston Q plays"preferably consists of a short length or section, N2, and its interior is made s mooth and hard in a suitable Inode. Tlius't of iron) it is enameled or plated; oi it'may be made of brass, 8mo. In this way the piston-valve Q'i's enabled to play accuratelyin the cylinder or section N', and also be comparatively free from wear.

The lower end of the rod M, or the under side of the piston-Q, is provided with means for enabling the rod M when depressed to take hold of the valve P or its connections and enable the said valve I? and its connections to be drawnup through and out of the pump-tube N and tube E for inspection, removal, repair, 85e., of the' working parts, and also to be placed in the tube and pushed down to place;-

A preferred means for enabling the rod M and valve I? to be connected or disconnected at pleasure consists as follows: The lower end of the rod`N is pointed, and behind the point V8 is provided with screw-thread V5. Thetop of arch qi' is provided with a vertical opening, g5, interiorly screwthreaded, and whose upper edge is beveled up and outwardly. Vhen the rod M is depressed, its point is guided by the beveled edge of opening g5 into said opening, and the rod then being rotated in the proper direction, the end ot rod M is screwed into the arch Q5. Then the piston Q and its connections can be lifted out. So, also, the valve P can be inserted into the pumpetube N and carried down to place on its seat, as o", and can then be disconnected from rod M by rotating the latter in the proper direction.

The coniiecting-rod M is to be divided. vinto lengths or sections of suitable length, and having suitable means whereby each section may be easily and quickly united to its adjacent length as the rod is lowered into the well, and be easily and quickly separated when the red is being removed from the well.

The lengths or sections ot' pipe or tube N `are td be connected in any desired manner.

. ward and inward to the inner edge of said up per end; also, the inner edge of the lower end of an uppeipsection is provided with a bevel, R, extending from within downward and out- 1 ward to the outer edge of said lastnamed lower end. These bevels are both of the same inclination, and when the said ends of said sections are brought together these bevels fit each other tightly, andthe inner surface of the tube at their point of junction presents a smooth and uninterrupted surface. ferred means of holding these beveled ends of said sections togetlier'is as follows: On the outside of tlie-adjacent'ends of the section s lof the pump-tube N isa screw-thread, and in uniting the sections the adjacent ends of both sections provided with screw-threadsare respectively screwed into a screw-coupling, T. The bevels R on the sections, and their mode of fitting into one another, aid in stitfening thejoint formed by thejunction of them and the screw-coupling T or the latters equivalent.

The advantages of having the bevels inclined from outside and below upward andinward is this, that the piston Q can be readily Alifted out and uithdrawn from t-lie pumptubing at the sanie time the upward-pointing end or edge V6 of the packing V cannot irnpinge against any resisting edge at the interior seam or juncture of thevjoint, and hence will not be stopped, wedged, or out by such seam, In insert-ing said Apiston the rounded well up through the cheek-valve P until it (the piston Q) has completed its upward stroke, at which time the space above cheekvalve P and below piston Q is full of liquid. The check-valve P'now closes and the actuating-rod descends, and pistons L and Q also descend. The liquid below piston Q passes through the valve of said piston Q and up above said piston Q until the actuating-rod has reached the lower end of its stroke. As the latter again rises the piston Q draws up liquid from the well in the manner aforementioned, and at the same time lifts the liquid above it and forces apart of said liquid up into cylinder K and against piston L; hence the liquid finds no outlet. The remainder of the liquid is forced througlispaee M between cylinder K and tube N, up through passage m and tubes I I into chambery of body-piece G, thence into chamber g of the bed A, and thence into discharge-tube 4, and thence it passes from the pump. The pump is new full of liquid, and as the actuating-rod descends the liquid resting on the clieck-valve l? rushes through piston Q, and at the saine time the piston L, descending, forces the liquid out of its cylinder K, up through the space m between cylinder K and tube N, through passage m into the tubes I I, and thence through cham- A pre- ICO n ber f/ and ehamber g' and through dischargetube 4. As thc actuating-rod rises the piston Q. again fills cylinder K with liquid and forces the remainder of liquid (which piston Q raises) out of the pump, as aforementioned, and the consequent descent of the piston L forces the liquid in cylinder l out of the pump, as aforementioned. Thus these operations are successively repeated as the pump is operated, and a continued stream is ejected from the discharge-orifice of the pump. The air vessel or chamber 5 contributes to make the stream more even in its continuous discharge. The proportion which the capacity ofthe cylinder I( with reference to its pistouand stroke bears to the capacity of' cylinder N and its piston and stroke is preferably as 1 to 2.

The waste-hole 3 in tube E performs a double function. Should liquid work up between the piston L and the inner side of tube K and through slot Z it would, after accumulating, till the tube E outside of tubes I I, and then, not being able to find egress, would resist the upward stroke of piston L and thus impede and pcrhapsaltogether stop the action of the pump.

The waste-hole in tube E'allows the egress of such liquid that perchance iuds its way into the tube E outside of tubes I. Furthermore, it is desirable that this pump should in cold climates be what is known as a nonfreezing pump.7 I therefore provide wastehole 2 in tube or tubes I, and when the pump Stops working the liquid in all of that portion of the pump which lies above waste-hole 2 will pass outJ of said hole, and then out of waste-hole 3 intube E, thus emptying the pump.

It may be well here to remark that the tubing of the pump above the openings 2 and 3 is sufficiently long to cause the said openings to lie below the frost-line.

Thepri mary advantages in the construction of this pump are, ii rst, that the pump is cheap, convenient, and efficient; second, the pump tubing or piping, as N, when formed-as it usually will be-in sections, can be readily put together and lowered into the well, and can also be readily raised and the various sections easily and quickly separated; third, all of the working parts of the pump can be readily and quickly inserted into the tubing or piping N and as quickly and readily withdrawn; and, fourth, the body-piece G, tubing I I, cylinder J, and cylinder K can be readily inserted in the pump along` with the working parts, and quickly and firmly set in position by set-screw j and bolts a, and can be readily withdrawn along with said working parts.

The various features of my invention are preferably employed together; but one or more of said features may be employed without the remainder; and, in so far as applicable, one or more of said features may be used in connection with pumps or pumping devices other than those herein-specifically described.

What I claim as new and of my invention, and desire to secure by Letters Patent, is-

l. rIhe combination of bed-piece A, having space D and chambery', and the body-piece G, having chamber g and the slot f, and V.setscrewj, and packing, substantial] y as and for the purposes specified.
